To all whom itmay concern." a

Be it known that I, FRANK GUY, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois,'have invented a new and useful Water-Feed Appliance for Acetylenetion.

calcium carbid. .7 h 1 I The feed attachment herein set forth is designed for use'on'lamps'of different makes and may be made and sol'das a separate I articleof manufacture,

--Acetylene lamps ofthe type to which this invention relatesgenerallycomprisea water reservoir, acarbidjbox, a feed tube intercom- .1

"the carbid box to convey water from the resinstances the valve is at the lower end of the 'municating between the'fwater reservoir and ervoirinto the box and a valve controlling the flow of water through the -tube.= In some tube, and in otherinstancesit is at the up- "per end 'of the tube.- Itis well knownto persons skilled in the art that efllorescence results from'the contact of the waterwiththe carbid, causing a moist ash'to accumulate in and around the lower end of the tube,

or around thefvalve' at-the' lower end of the,

tube as the case may be, and when the ash I pletely chokes the tube so that water cannot pass through it;or surrounds the valve and* causes it to stick on the valve seat thus st0pping the, flow of water through the tube so that itis necessary'to frequently rotate the valve to break up the incrustation and re store the feed. g'

{purposes of; my invention are: to provide in connection with the feed tube, a plurality;

of coordinated receiver tubes adaptedtoreceive water 'well'above the ash in the box" "'thro' ugh the ash into the carbid; 't-o-provide simple and eifectivefmeans' for connecting the receiver tubes with'the feed tube-1so-that-- the latterffmaybe manuallyrotated-on the;

cording to circumstances; 1 p

I prefer to useayalve 1-3 as describedfor v1 and apply it'on a distributer extending former; and to'provide a distributer 'of a which the following is a specifica-' cited in the claim.

The invention relates primarily to feed appliance in place on'the feed tube ofan appliances for acetylenelamps such as are commonly used by miners and others, but -may be applied with equal advantage to, {other lamps adapted to generate acetylene gas by the controlled'application of waterto.

The same reference ,numerals designate the same parts in all the views.

The lampmaybe ofgany suitable material,

j preferably light sheet metal, strong enough to withstand the pressure of the generated so} i gas and preferably comprises a water reservoir -1, a carbid box 2, a stationary. diaphragm 3, united with the res'ervoir,-a' screw member'fi on the reservoir 1, acomplemental screw'member 6 on the box 2 engaging with the'screw member 5 toconnect the boxwith the reservoir so that-boxmay be detached to admit 'carbid into the box, an opening 7 to admit water to the reservoir, a cap 8 closing theopening 7 a vertical feed-tube 9 permanently' attached to the: diaphragm and having at one/end a flared valve seat 12, a tapered valve'plu'g 13 fitted vto the seat 12,

a valve stem 14 permanently attached tothe.

plug 13, and vhaving a screw-threaded part 15, adapted toengage'in a femalescrew. 16 on the top ofthel reservoir, and a'han'dle 17 usable for rotating the valve stem inone direction topress the-plug 13 against the seat 12 to close the valve, and rotating it in the opposite direction to remove the plug, from the seatto open the valve, more or less, ac-

first control of the water in the tube but the feed regulation would be efiective without.

. the valve and it obviously may be omitted 1 tween the tubes are greatly exaggerated in without departure from my invention. r The feed tube 9 has a series of circumferential grooves 23, 24;, 25. Thefeed-attachment' proper comprises three co-axial slightly tapered receiver tubes 18, 28, and. 31, adapted to slide and rotate on thefeedtube and adapted-to receive water from-the "feed-tube and conduct it downward along the respective receiver tubes in a manner to rosive metal spaced slightly apart from each other to permit a very restricted flow of For the sake of the drawing, it is expressly designed howpassing between and around the tubes shall be justsufiicient for the proper generation of gas when applied to the mass of carbid 36 in the'box 2. The receiver tube 18 has at its upper end springy fingers 26, separated by spaces 27,"

the fingersbeing adapted to engage in the groove 24: to support the receiver 'tube on,

and permit it to rotate around the feed tube.

At the lower terminal of the tube 18 is a tapered member 19 adapted to easily enter; and conduct water to the carbid, and also serving to close the end of thetube and 'form' achamber'20 to contain water, which in due course fills the tube, overflows through the spaces 27 between the fingers26, and fiowsj downward along {the outer surface 'of' the tube.

A' circumferential ledge 21, around the lower part of the receiver tube, is adapted to catch and difi 'use water dropping from all the receiver tubes 18, 31; and 28." Flirtin'gs 22 in the member 21 facilitate the manual rotat on of the tube and cause uniform distribution of the water.

r The outer receiver tube 28 has springy fingers 29 spaced'apart-fromeach other and adapted-toe ngage inthe groove23 to support the receiver tube and permit itto rotate" on the feed tube 9. The intermediate"- receiver tube 31 has springy fingers 32 separatedby spaces 33 and adapted'to engage 1n the groove" 25 to support the receiver tube" and permit it to rotate on the feed-tube9. It will benoted that there arethree out lets "for the water one 'abovethe other. If

'the lower opening becomes clogged, the in-j' termediate opening willstill admit a suit able quantity of water and if the lower opening and the intermediate opening bothbecome'clogged the upper opening will still' admitia s'uflicient: quantity of water. '1 The" "and 31 having springy ever'that the spaces between the tubes shall Y be so restricted that the quantity of water washed out.

. openings at the top of the respectivereceiver tubes permit the escape of air and obviate air pockets in the tubes which might stop the'flow of water in the tubes if air vents were not provided. The springy connections ofthe receiver tubes with the feedtube of the lamp admit of placing the receiver tubes on the feed tube and rotating embodiment of the invention, illustrated in Figs. 3, 4 and 6, comprises a feed-tube 9 provided with circular grooves 24 and 25, a

'valveg37 seating on the upper {end of the.

feed-tube, two "coordinated receiver tubes 18 fingers, and a distributer 19 having a chamber 20 and a'ledge 21. The receiver tubes 18 and 31 are rotative on the feed-tube 9 as already described. 5'

Mode of operation:

, Upon opening the valve'13; water from the feed-tube 9 will fill the receiver tube 18 V and overflow through-the spaces 27 between the fingers 26 and will trickle downward on.

the outer surface of the tube 18 and "fall upon the ledge 21 :mdgravitating downward from the ledge will be diffused in the mass of carbid. If the space34c between the receiver tubes 18 and 31 should become so ward along the outer surface of the receiver tube 18 ,the over-flow from the tube 18 would fill the space 3 1. and would overflow the 'up-' per'end ofthe intermediate receiver tube 31, and would trickle slowly down the outer surface of the tube 31', and trickling on the clogged asto' stop the flow o'fw'ater downledge 21 would'be diffused in themass of.

carbid. Ifthe space 35 between-the receiver" tubes 31 and 28 should become so clogged as 'to stop'the escape of water fromthe space, the water accumulating 'inthe space To break up the accretion and remove it from the spaces'34and 35,- the reservoir will other hand tobreak' the' accretion so that upon turning on the water it maylbe easily The operation ofthe attachmentofmodi foregoing description. p

The use of a plurality of coerdinatedre ceivertubes co acting with one distributer bbvia'tes the risk of frequent stoppage 'of the would overflow the outer receiver tube 28 and would trickle downward along its outer surface and would fallonthe-ledge 21 and be distributed'in the mass ofcarbi'd.

' fie'd construction will be obvious from'the skilled in the art.

Having fully described my invention, what I claim as new and desire to secure by Let-' ters Patent is:

A water-feed appliance for acetylene lamps, comprising a feed tube having external circumferential grooves; a vertical 15 series of manually rotative coordinated receiver tubes open at both ends and having I spring connections engaging in the circumferential grooves of the feed tube; and a cone-pointed circular distributer having a I fluted ledge extending outwardly beyond the circumference of the uppermost receiver tube and adapted toreceive over-flow from any of the receiver tubes. 7 r

In witness whereof I have hereunto signed my name at Springfield, Illinois, this 16th 25' day of October, 1918. a
